Declaration of Performance

Three component epoxy resin to waterproof both with negative and positive pressure, to be used as osmotic over undergorund walls, to encapsulate rising dampness and to achieve a vapor barrier on wet supports.

5 kg - 0.86 gal plastic bucket
10 kg - 1.73 gal plastic bucket

Epoxy-cement waterproofing characterized by high resistance to negative pressure. Product suitable on tunnels, cellars, basements, garages, elevator shafts, underground rooms and any wet support or surface affected by rising dampness.

Compared to traditional systems, that requires thicknesses not smaller than 1.5 cm - 1.18 inch, this product guarantees an excellent waterproofing with just 2.5 – 3.0 mm / 0.10 - 0.12 inch. Its extreme versatility allows to use it as vapour barrier for wet supports, as encapsulating for rising dampness and saltpeter and as a real waterproofing in counterthrust.

It can be applied by roll, brush or spatula and once dried it can be coated with plasters, smoothers, resins, adhesives, coatings, tiles or paints; because it also acts as an adhesion coadjuvant.

  • Versatility of use
  • Resistant up to 9.5 ATM of negative pressure (counterthrust)
  • Resistant up to 9.5 ATM of positive pressure
  • Adhesion on any kind of surface
  • It allows to waterproof permanently applying just few millimeters
  • It achieves a good adhesion bridge for any plaster, glue or finishing coat
  • Excellent salt resistance
  • Applicable even during winter (up to +5°C - 41°F)
  • Ageing resistance
  • No maintenance needed
